cabling choices, network interface devices such as switches and routers, patch panels, and so forth need to be specified and installed with care.<\/p>\n\n\n\n<p>Most often, it is the simple things that will trip an installer up. \u00a0The one area where I have found the most mistakes made is the pair&#8217;s connection to various termination points. \u00a0There are two basic standards, TIA\/EIA T568A and T568B. \u00a0Neither is better than the other, both are often identified on terminating devices such as jacks and patch panels. \u00a0The most important aspect of these standards for an installer is to pick one and stick with it.<\/p>\n\n\n\n<figure class=\"wp-block-image alignnone\"><a href=\"https:\/\/www.engineeringradio.us\/blog\/wp-content\/uploads\/2011\/01\/T568.jpg\"><img loading=\"lazy\" decoding=\"async\" width=\"650\" height=\"343\" src=\"https:\/\/www.engineeringradio.us\/blog\/wp-content\/uploads\/2011\/01\/T568-650x343.jpg\" alt=\"TIA\/EIA 568 color code\" class=\"wp-image-2206\" srcset=\"https:\/\/www.engineeringradio.us\/blog\/wp-content\/uploads\/2011\/01\/T568-650x343.jpg 650w, https:\/\/www.engineeringradio.us\/blog\/wp-content\/uploads\/2011\/01\/T568-150x79.jpg 150w, https:\/\/www.engineeringradio.us\/blog\/wp-content\/uploads\/2011\/01\/T568-300x158.jpg 300w, https:\/\/www.engineeringradio.us\/blog\/wp-content\/uploads\/2011\/01\/T568-400x211.jpg 400w, https:\/\/www.engineeringradio.us\/blog\/wp-content\/uploads\/2011\/01\/T568.jpg 690w\" sizes=\"auto, (max-width: 650px) 100vw, 650px\" \/><\/a><figcaption class=\"wp-element-caption\">TIA\/EIA 568 color code<\/figcaption><\/figure>\n\n\n\n<p>When certifying networks, the most common problem I have encountered is crossed pairs. \u00a0Almost invariably, one end will be punched down with the A standard and the other with the B standard. \u00a0Jacks are particularly difficult, as the color-coding stickers show both. \u00a0Many patch panels have a slide-out, reversible card with is an either\/or situation. \u00a0For some reason, I have stuck with the B standard, and on any project I am managing, I get rid of all the A color codes I can find and tell the installers that B is the only acceptable termination standard. \u00a0That cuts down on a lot of errors and redos during certification. \u00a0That is good, it saves time and I hate redos.<\/p>\n\n\n\n<figure class=\"wp-block-image alignnone\"><a href=\"https:\/\/www.engineeringradio.us\/blog\/wp-content\/uploads\/2011\/02\/CAT-5E-Wall_Outlet.jpg\"><img loading=\"lazy\" decoding=\"async\" width=\"638\" height=\"584\" src=\"https:\/\/www.engineeringradio.us\/blog\/wp-content\/uploads\/2011\/02\/CAT-5E-Wall_Outlet.jpg\" alt=\"Cat 5e wall jack set\" class=\"wp-image-2287\" srcset=\"https:\/\/www.engineeringradio.us\/blog\/wp-content\/uploads\/2011\/02\/CAT-5E-Wall_Outlet.jpg 638w, https:\/\/www.engineeringradio.us\/blog\/wp-content\/uploads\/2011\/02\/CAT-5E-Wall_Outlet-150x137.jpg 150w, https:\/\/www.engineeringradio.us\/blog\/wp-content\/uploads\/2011\/02\/CAT-5E-Wall_Outlet-300x274.jpg 300w, https:\/\/www.engineeringradio.us\/blog\/wp-content\/uploads\/2011\/02\/CAT-5E-Wall_Outlet-400x366.jpg 400w\" sizes=\"auto, (max-width: 638px) 100vw, 638px\" \/><\/a><figcaption class=\"wp-element-caption\">Cat 5e wall jack set<\/figcaption><\/figure>\n\n\n\n<p>You can see that this color code marking can lead to confusion. \u00a0I take a sharpie and cross out all the A markings to avoid installation mistakes.<\/p>\n\n\n\n<p>Incidentally, on any new network installation, <a rel=\"noopener\" href=\"http:\/\/en.wikipedia.org\/wiki\/Category_6_cable\" target=\"_blank\">Category 6<\/a> cable should be used. \u00a0As more and more data throughput is required for network applications, \u00a0Category 6 Cabling has better performance specs and will likely have a longer service life than another cable. \u00a0 It may be a little bit more expensive than Cat 5, \u00a0however, well worth the investment. \u00a0It would be a great mistake and a waste of money to have to pull out the network and reinstall it in a few years because the cabling doesn&#8217;t have the required bandwidth.<\/p>\n\n\n\n<p><a href=\"http:\/\/en.wikipedia.org\/wiki\/Category_7_cable\" target=\"_blank\" rel=\"noopener\">Category 7<\/a> cabling is in the works.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Radio stations more and more revolve around networked computers. &nbsp;Engineers need to understand computer networking, especially as it relates to audio distribution and playback. &nbsp;Eventually, I see broadcast engineers being more computer science types rather than electrical engineering majors.
